3.4/ 5 average rating with 93 reviewsforErygel
Upsides
  • You only need to apply it once a day, usually in the evening.
  • Most people who reported having skin irritation said that it was mild.
  • Part of a complete program to help you take better care of your skin.
  • Applying erythromycin to the skin reduces the amount of acne bacteria and "calms" the skin down (lowers the inflammatory response) in acne.
  • Available in a gel formulation which may be better if your skin is very oily.
  • Better choice if you're pregnant. erythromycin is categorized as pregnancy Category B (likely safe) as compared to similar topical medicines that are Category C (weigh risks vs benefits).
Downsides
  • It may take up to 6 months to see the full benefit for facial wrinkles.
  • Not a good choice for women who want to become or are pregnant
  • Can change the color and texture of your skin if used long-term.
  • You need to be careful about avoiding any sunlight or artificial tanning while using it.
  • It doesn't work for deep wrinkles.
  • There's a risk of irritation with anything you apply to your skin and this is no different. erythromycin, like other topical antibiotics, can cause skin irritation and may appear as redness, peeling, abnormal dryness or stinging, tightening, or burning sensations.
  • It's rare, that a serious allergic reaction would occur, but it's a good idea to test a small area of skin before using on any larger or sensitive areas
  • Studies show it works better when combined with other topical medicines to fight acne and reduce the risk of it losing its effectiveness over time.
  • Can cause severe inflammation of the large intestine (pseudomembranous colitis)
  • Stop using if you don't notice any improvement in your acne after 6-8 weeks. The most time you can use it is three months.
